MOTOR-PLOW.

Specification of Letters Patent.

Patented March 30, 1909.

Application filed September 28, 1908. Serial No. 454,363.

To all whom it may concern:

Be it known that we, JAMES PATERSON and WILLIAM PATERSON, citizens of the United States, residing at Fresno, in the county of Fresno and State of California, have invented new and useful Improvements in Motor-Flows, of which the following is a specification.

Our invent-ion relates to improvements in lowing apparatus.

t consists in the combination ofparts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure. 1 is a side elevation of the apparatus. Fig. 2 is an enlarged view of the rear portion. Fig. 3 is a plan view.

It is the object of our invention to provide a disk plowing apparatus, in which a series of disks are so mounted and actuated as to be successively and intermittently introduced into the soil and raised therefrom, said disks being revolved during their passage through the ground, and acting to assist in propellin the apparatus, in addition to their main motion.

' Various mechanism may be employed to Vv'e have in the present case shown a mechanism which will produce satisfactory results.

In the drawings, A is a frame or carriage mounted upon wheels 2, and this carria e may be im elled over the land, preferably by a suita'b e motor; but it might be hauled by a team of animals.

3 is a supplemental plow frame. This frame is pivotally attached to the main frame of the motor-vehicle by means of a countershaft 4, revoluble inside of the ivot-boxes 5 which form the connection etween the two frames, andabout which the plow frame is movable to follow the irregularities and undulations of the surface over which it passes.

We have in the present case indicated a motor 6, from which power may be derived to drive the apparatus, and to operate the plows.

The plows consist of disks 7 which are independently mounted upon the lower ends of pitmen 8. The upper ends of these itmen are connected by arms or walkingams 9, with a fixed support orgsupports 10, carried upon the frame 3. 'The intermediate portions of these pitmen are com nectcd with crank 11 upon a crank-shaft 12 journaled upon the frame 3, so that as thecrank is revolved, the pitmen and the disks are carried around with the cranks; the disks thus making a forward circular sweeping movement which raises them out of the ground, as they advance, and iihen depresses them into the ground as they move rearwardly.

Power to drive the crank-shaft may be derived from the motor in any suitable manner. lVe have here shown the sprocketchain 13 passing around pulleys 14, one of which is concentric with the fulcrum-shaft 4 between the two frames, and the other mounted upon the crank-shaft or shafts.

The cranks may be of any suitable or desired number, depending upon the power of the motor and the work to be done. They are preferably arranged equidistant'around the crank-shaft, and at proper distances apart to suit the width of'the furrows required.

The speed of the crank or eccentric shaft may be regulated with relation to the forward movement of the machine tdsuit the condition of the work to be done; and it will be seen that the movement of the crankshaft connecting through the pitmen to carry the disks throughthe arcs of motion previously described, will successively force the disks into the ground, and the disks being revoluble, as hereafter described, the'backward movement through the ground, will cause them to revolve upon their axes, and thus turn furrows during their passage through the ground. This action is also an important assistance toward propelling the apparatus; and the speed at which the disks travel being greater than the actual forward travel of the machine, it will be seen that they act in addition tothe turning of the soil, to impel the machine, and reduce the actual tractive effort necessary to be applied to the. driving wheels.

. The number of cranks used will be determined b the power of the motor, and the work to e done,- and the speed of revolution of the crank-shaft may also be regulated to suit conditions of the work.

The rear of the frame 3 is here'shown as supported upon the caster-wheel 15-, which may also serve as a gage-wheel.

The frame 3 may be raised or depressed with relation to this wheel by means of a lever 16, which connectswith a vertically disposed sleeve 17 movable upon the stem or spindle 18 of the caster-wheel. The front end of the lever 16 is pivoted orfulcrumed as shown at 19. Y

20 is a toothed segment; 21 is a'pawl actuated by aconnecting rod 22, and a grip lever 23 contiguous to the handle of the lever '16, so that by disengaging the pawland moving the lever 16', the rear of the frame 3 may be raised or depressed with re lation to the caster-Wheel, and the depth to which the ulated.

plows enterjthesoil is also reg- The disks 7 are journal ed upon bearings 24, which are formed in the lower ends-of the pitmen 8 at such angles that the disks will stand at an angle of about more or less, to the plane of travel of the pitrnan arms, and also at an oblique angle to the shank of the pitmanso as to give "the proper sharelike set to the disk; and the rear or convexed portions of the disks have studs which are turnable upon these hearings, so that the ground.

' disks rnay revolve freely when they enter the 25 are colters, which also form landsides.

They are attached to the extreme lower end and to one side of the itman 8, and inaddition to forming the co ters to cut the side of with a crank-shaft.

the furrow down square, they also form land-. sides and counteractthe side thrust of the disks. ,As the bearing-studs project from;

the convex-sides of the disk, the concave sides will be perfectly smooth and plain perform their service when passing throu the'soil. T

'We have found that the best results are obtained by connecting a plurality of' In the present casewa; have shown three cranks to a gang, the} cranks being substantially equi-distant from each other, in the circle of their travel, and if' more than one set is desired, the second set of disks will be carried by an independent; shaft set slightly behind and out of line with the first orie and a third set again by another crank-shaft thus increasing the number of? crank-shafts, and operating the plowing disks Each crank-shaft will receive" in; groups.

ower by which to revolve it from the motor 8y means hereafter described.- I The operation will 'then be as follows: The apparatuslwhich carries the crankeshfaftor shafts, being drawn over the ground, andv the shaft caused to rotate by suitably connected mechanism, the'upp'er endsof the pitmen arms will be given a rising and movement by means of the walldng-beaiiis 9; while the disks carried at the lowerends'of the pitmen will be given a slightcjichidal movement, first advancing above mammaof the ground, then being f depressed ,"and forced into the ground, one after-Itheother,
